Skip over iteration in Enumerable#collect

Question

(1..4).collect do |x|
  next if x == 3
  x + 1
end # => [2, 3, nil, 5]
    # desired => [2, 3, 5]

If the condition for next is m

Answer 1

just a suggestion, why don't you do it this way:

result = []
(1..4).each do |x|
  next if x == 3
  result << x
end
result # => [1, 2, 4]

in that way you saved another iteration to remove nil elements from the array. hope it helps =)
